lWhen a series ol plates is tn he doubled` they are placed on the. iioor il. below the. knife and as it is desirable te have all the plates in alignment m' matched. a rnatchinnT mechanism is prnvided to co-act with the doublingF apparatus.

Vlhe carriages 4G and 47, which are slidahly mounted in guides 4S and at), so as te rnove toward and away ltroni the plates. have lugs 50 and 5l, which project downwardly through guides l?? and 49 and are connected to levers forming; the carriage eperatinp; mechanism. The lug` .30 on the carriage 6 is pivotally connected hy a short link i'ite the upper end of a rocking' lever 59a, the rocking lever losing keyed er otherwise secured at an iinernediate point in its length te a reciting shalt 54p which is jeurnaled on the hearing` bracket. 55.

'lhe lugs Tl on the carriages lil are piv otally connected by the links to the upper ends of the rocking levers 8?). which are pivotally mounted at a point adjacent to their lower ends on the brackets 8%. rllhe levers 552% are pivotally connected at their lower ends7 by links 85, to the lower end of the rocking levers 76, or end opposite that to which the links T5 are secured.

lt will be apparent that when duid pressure is admitted to the lower-end of the cylinder 8l the piston rod 8O will move upwardly and cause the several levers to pull on and move the stops or lingers 42 and i3 toward and against the side edges of the plates to be matched.

The fingers 42 and el?) are arranged to be retracted or moved away from the edges of the matched plates by the' springs 88 and 89. these springs having one end an chored to the shaft `77 and the other end thereof secured to the lower ends of the rocking levers 73 and 83 (see Figure l).

Ilhe general operation of this doubling mechanism will be readily understood by those skilled in the art.

Attention is directed however, to the fact that. the sheets are doubled by a downward movement thereof, between the rolls 7 and 7a instead of moving upwardly. By doubling the sheets downwardly the opera tion is facilitated and the sheets are more closely doubled. since the packs of sheets have a curved formation as they come from the rolls. and when doubled upwardly this curve in the plates acts as a spring and prevents the plates being doubled closely together. lt will also be noted that by doubling the sheets downwardly the major portion of the mechanism may be mounted in a pit below the floor level, thus saving valuable door space in the mill.

1While one specific embodiment of our invention has been illustrated and described it will be understood that various changes may be made in the design and structure and by the substitution of equivalents, without departing from the spirit of the invention as defined in the appended claims.
